Thanks SVS,

 

this is how I would attach this problem,

 

I had to look it up but I also have     2000 pounds in a US ton   .  

 

We have      \(\frac{x \;hours}{y \;pounds},\qquad \frac{2000\;pounds}{1\;ton}\qquad 1 ton,\qquad ?hours\\~\\ \)

 

      

 

I want   hours,   I want to cancel out all the other units.

 

\(\frac{x\;hours}{y\;pounds}\times \frac{2000\;pounds}{1ton}\times 1ton=\frac{2000x}{y}\;hours\)
